Yeah you would think so, it's just that I already have the boost and temp gauges from ten years ago and the way u set them is to move the needle to where u want the warning light to come on and if the guage reads over that, on comes the warning light.
However if I set the gauge at say 1-2 bar( it reads to about 10 bar) then anything over 1-2 bar will see the light come on, which is the opposite to what I obviously want. I may just have to install it and see
